I think that it will be difficult because there are probably two pieces. The tines will have a rectangular "shaft" that is inside the wood and then surrounded by the exterior piece that you see. I would try to repair the handle first. Not your question I know.
Good looking Buddy, reminds me of my late great best friend Yogi
The fork has a tang that is driven into a hole in the end of the wood handle. The sheet metal ferrule is not salvageable. Just hold what's left of the handle and drive the fork off with alternate hammer blows to opposite sides of the fork bar. We buy the same forks up here and drive them off the handles, then heat the tangs red hot and bend them over 90 degrees and then re attach the handles after shortening them to make our clam hoes.
